Eine ähnlich aufgebaute Lenksäule ist aus der
Aufgabe der Erfindung ist es, eine motorisch verstellbare Lenksäule der eingangs genannten Art anzugeben, die einen vereinfachten Längenausgleich bereitstellt.The object of the invention is to specify a motor-adjustable steering column of the type mentioned at the outset, which provides simplified length compensation.
Die Lösung der gestellten Aufgabe ergibt sich aus den Merkmalen des Anspruchs 1. Vorteilhafte Ausgestaltungsformen sind in den Unteransprüchen beschrieben.The solution to the problem posed results from the features of claim 1. Advantageous embodiments are described in the dependent claims.
Die Stelleinheit ist über einen Schwenkhebel mit der Halteeinheit gekoppelt, wobei der Schwenkhebel an der Stelleinheit und an der Halteeinheit verschwenkbar angelenkt ist. Somit ist der Schwenkhebel verschwenkbar an der Stelleinheit angebracht und weiterhin ist der Schwenkhebel verschwenkbar an der Halteeinheit angebracht. Der Schwenkhebel ist weiters mit dem ersten motorischen Antrieb gekoppelt. Durch das Betreiben des motorischen Antriebs wird der Stellhebel verschwenkt, so dass das Verschwenken des Stellhebels zu einem Verschwenken der Stelleinheit relativ zur Halteeinheit führt.The actuating unit is coupled to the holding unit via a pivoted lever, the pivoted lever being articulated in a pivotable manner on the actuating unit and on the holding unit. Thus, the pivoting lever is pivotally attached to the setting unit and further, the pivoting lever is pivotally attached to the holding unit. The pivoted lever is also coupled to the first motorized drive. By operating the motorized drive, the adjusting lever is pivoted, so that the pivoting of the adjusting lever leads to a pivoting of the adjusting unit relative to the holding unit.
Gemäß der Erfindung ist die Stelleinheit in ihrem dem ersten Endbereich entgegengesetzten zweiten Endbereich mit einem elastischen Bügelelement versehen, welches zur Befestigung am Fahrzeugchassis vorgesehen ist und durch elastische Verformung sowohl eine Verschwenkung der Stelleinheit um eine Schwenkachse als auch eine Verschiebung der Stelleinheit in Richtung der Drehachse (9) zulässt. Somit ermöglicht das Bügelelement eine Schwenkbewegung der Stelleinheit um die Schwenkachse und bietet gleichzeitig die Möglichkeit des Längenausgleichs. Unter der Schwenkachse ist im Sinne der Erfindung nicht eine körperliche Schwenkachse zu verstehen, sondern die Achse, um die die Stelleinheit herum verschwenkt wird. Somit stellt die Schwenkachse eine Achse im mathematischen Sinn dar und ist somit durch eine Gerade gebildet, um die die Stelleinheit verdrehbar ist. Des Weiteren erfüllt das erfindungsgemäße Bügelelement auch die Funktion der Anbindung der Stelleinheit an das Fahrzeugchassis.According to the invention, the actuating unit is provided in its second end region, opposite the first end region, with an elastic bracket element which is provided for attachment to the vehicle chassis and, by elastic deformation, allows both pivoting of the actuating unit about a pivot axis and displacement of the actuating unit in the direction of the axis of rotation ( 9) allows. The bracket element thus enables a pivoting movement of the actuating unit about the pivot axis and at the same time offers the possibility of length compensation. In the context of the invention, the pivot axis is not to be understood as a physical pivot axis, but rather as the axis about which the actuating unit is pivoted. The pivot axis thus represents an axis in the mathematical sense and is thus formed by a straight line about which the actuating unit can be rotated. Furthermore, the bracket element according to the invention also fulfills the function of connecting the actuating unit to the vehicle chassis.
Bevorzugt ist die Schwenkachse nicht als starre Achse ausgebildet, sondern als verlagerbare Momentanachse. Somit nimmt die Schwenkachse abhängig von der Verstellposition eine andere Position. Die Momentanachse ist die Achse, um die die Stelleinheit im Moment (Zeitpunkt, infinitesimal) als nur drehend angesehen und behandelt werden kann. Die Geschwindigkeit in der Momentanachse ist im betrachteten Augenblick null oder wäre es, wenn sich die Stelleinheit bis zum Momentanachse ausdehnen würde.The pivot axis is preferably not designed as a rigid axis, but as a displaceable instantaneous axis. The pivot axis thus assumes a different position depending on the adjustment position. The instantaneous axis is the axis about which the actuator at the moment (point in time, infinitesimal) is considered and treated as only rotating can be. The speed in the instantaneous axis is zero at the moment under consideration, or it would be if the actuator were to extend to the instantaneous axis.
Gemäß einer bevorzugten Ausführungsform umfasst das Bügelelement ein Metallblech, vorzugsweise ist es aus einem Metallblech gebildet. Es kann vorgesehen sein, dass das Bügelelement aus einem Federstahl gebildet ist. Ein solches Material bietet die zur sicheren Anwendung der Stelleinheit an das Fahrzeugchassis nötigte Festigkeit und gleichzeitig die für den Erfindungszweck erforderliche Elastizität. Des Weiteren eignet sich das genannte Material besonders gut für eine weitere vorteilhafte Ausgestaltung der Erfindung, wonach das Bügelelement als Stanz-Biegeteil ausgestaltet ist.According to a preferred embodiment, the bracket element comprises a metal sheet, preferably it is formed from a metal sheet. Provision can be made for the bracket element to be formed from spring steel. Such a material offers the strength required for safe application of the actuator to the vehicle chassis and at the same time the elasticity required for the purpose of the invention. Furthermore, the material mentioned is particularly suitable for a further advantageous embodiment of the invention, according to which the bracket element is designed as a stamped and bent part.
In einer weiteren vorteilhaften Ausgestaltung der Erfindung weist das Bügelelement eine Dicke (Materialstärke) mit einem Wert zwischen 0,5mm und 3mm auf.In a further advantageous embodiment of the invention, the bracket element has a thickness (material strength) with a value between 0.5 mm and 3 mm.
Das Bügelelement kann in einer vorteilhaften Ausführungsform derart ausgelegt sein, dass bei der Verschwenkung der Stelleinheit um die Schwenkachse von maximal 5° sowie einer gleichzeitigen Verschiebung der Stelleinheit in Richtung der Drehachse von maximal 5mm sich das Bügelelement elastisch verformt.In an advantageous embodiment, the bracket element can be designed such that the bracket element deforms elastically when the actuating unit is pivoted about the pivot axis by a maximum of 5° and a simultaneous displacement of the actuating unit in the direction of the axis of rotation by a maximum of 5 mm.
In weiterer vorteilhafter Ausgestaltung ist das Bügelelement mittels einem oder mehreren Befestigungselementen an der Stelleinheit befestigt. Dies ermöglicht eine kostengünstige Herstellung des Bügelelementes, beispielsweise als separates Stanz-Biegeteil, welches anschließend auf einfache Weise an der Stelleinheit befestigt wird. Als Befestigungselemente kommen vor allem Schrauben oder Niete infrage.In a further advantageous embodiment, the bracket element is fastened to the actuating unit by means of one or more fastening elements. This enables the bracket element to be produced inexpensively, for example as a separate stamped and bent part, which is then attached to the actuating unit in a simple manner. Screws or rivets are particularly suitable as fastening elements.
Die Erfindung umfasst aber auch andere Befestigungsarten wie Kleben, Klemmverbindungen, Formschluss oder Verbindungen durch Umklammern oder Verformen von Befestigungselementen, die entweder am Bügelelement selbst oder an der Stelleinheit ausgebildet sind. In einer alternativen vorteilhaften Ausführungsform ist das Bügelelement unlösbar mit der Stelleinheit verbunden. Diese Verbindungsart ist besonders belastbar.However, the invention also includes other types of fastening such as gluing, clamping connections, positive locking or connections by clasping or deforming fastening elements, which are formed either on the bracket element itself or on the actuating unit. In an alternative advantageous embodiment, the clip element is permanently connected to the actuating unit. This type of connection is particularly resilient.
In weiterer vorteilhafter Ausgestaltung der unlösbaren Verbindung ist vorgesehen, dass das Bügelelement mittels eines Fügeverfahrens an der Stelleinheit befestigt ist. Dies kann insbesondere durch Schweißen oder Löten erfolgen.In a further advantageous embodiment of the non-detachable connection, it is provided that the clip element is fastened to the actuating unit by means of a joining method. This can be done in particular by welding or soldering.
Eine weitere alternative vorteilhafte Ausführungsform sieht vor, dass das Bügelelement und die Stelleinheit als einstückiges integrales Bauteil ausgestaltet ist. Bei dieser Ausführungsform können sowohl Befestigungselemente als auch der Arbeitsschritt der Befestigung des Bügelelements an der Stelleinheit während der Fertigung der Lenksäule eingespart werden.A further alternative advantageous embodiment provides that the bracket element and the actuating unit are designed as a one-piece integral component. In this embodiment, both fastening elements and the work step of fastening the bracket element to the actuating unit can be saved during manufacture of the steering column.
In einer vorteilhaften Weiterbildung weist das Bügelelement einen Biegeabschnitt auf, dessen unterer Endbereich mit der Stelleinheit verbunden ist und der an seiner Oberseite in einen abgewinkelten Befestigungsabschnitt zur Befestigung am Fahrzeugchassis übergeht.In an advantageous development, the bracket element has a flexible section, the lower end area of which is connected to the actuating unit and which transitions at its top into an angled attachment section for attachment to the vehicle chassis.
Gemäß einer weiteren vorteilhaften Ausgestaltungsform weist das Bügelelement einen sich im Wesentlichen parallel zu einem gegenüber der Drehachse der Lenkwelle orthogonal angeordneten Ebene erstreckenden Biegeabschnitt auf, dessen unterer Endbereich mit der Stelleinheit verbunden und der an seiner Oberseite in einen abgewinkelten Befestigungsabschnitt zur Befestigung am Fahrzeugchassis übergeht. Infolge seiner geometrischen Ausrichtung kann sich der mit der Stelleinheit verbundene Biegeabschnitt bei einer Höhenverstellung der Lenksäule sowohl um eine horizontale Achse verschwenken als auch in Axialrichtung federnd nachgeben, um den gewünschten Längenausgleich zu gewährleisten. Der Befestigungsabschnitt ist um einen an die Bauform des Fahrzeugchassis angepassten Winkel abgewinkelt, damit er parallel zu dem dafür vorgesehenen Befestigungsbereich des Fahrzeugchassis ausgerichtet ist.According to a further advantageous embodiment, the bracket element has a flexible section which extends essentially parallel to a plane arranged orthogonally to the axis of rotation of the steering shaft, the lower end area of which is connected to the actuating unit and which transitions at its upper side into an angled attachment section for attachment to the vehicle chassis. Due to its geometric orientation, the one with the Adjusting unit-connected bending section pivot at a height adjustment of the steering column both about a horizontal axis and resiliently yield in the axial direction to ensure the desired length compensation. The fastening section is angled at an angle adapted to the design of the vehicle chassis, so that it is aligned parallel to the fastening area of the vehicle chassis provided for this purpose.
Mit Vorteil weist der Biegeabschnitt eine zentrale Ausnehmung auf, wodurch die "Federkonstante" des Biegeabschnitts verringert wird, um die insbesondere für den Längenausgleich erforderliche Verformung des Biegeabschnitts mit geringerem Kraftaufwand zu ermöglichen.The flexible section advantageously has a central recess, as a result of which the "spring constant" of the flexible section is reduced in order to enable the deformation of the flexible section, which is required in particular for length compensation, with less expenditure of force.
In einer vorteilhaften Weiterbildung kann das Bügelelement zumindest eine Verstrebung aufweisen. Durch eine solche Verstrebung kann die Steifigkeit des Bügelelements entsprechend den angestrebten Anforderungen angepasst werden. In weiterer vorteilhafter Ausgestaltung ist die zentrale Ausnehmung mit kreuzförmig angeordneten Verstrebungen versehen. Diese erschweren unerwünschte Verbiegungen des Biegeabschnitts in anderen als den vorgesehenen Richtungen.In an advantageous development, the bracket element can have at least one strut. Such a strut allows the rigidity of the bracket element to be adjusted in accordance with the desired requirements. In a further advantageous embodiment, the central recess is provided with struts arranged in the shape of a cross. These complicate undesired bending of the bending section in directions other than those intended.
Alternativ oder zusätzlich kann das Bügelelement Sicken aufweisen, die ebenfalls der Anpassung der Steifigkeit dienen können. Eine weitere vorteilhafte Ausgestaltung der Erfindung sieht vor, dass in der Stelleinheit ein Mantelrohr aufgenommen ist, welches mittels eines zweiten motorischen Antriebs gegenüber der Stelleinheit axial verschiebbar ist und welches die Lenkwelle drehbar lagert. Diese Maßnahme ermöglicht neben der Höhenverstellung des Lenkrads auch die Längsverstellung in Axialrichtung der Lenkwelle.Alternatively or additionally, the bracket element can have beads, which can also be used to adjust the rigidity. A further advantageous embodiment of the invention provides that a jacket tube is accommodated in the actuating unit, which can be displaced axially relative to the actuating unit by means of a second motor drive and which supports the steering shaft in a rotatable manner. In addition to the height adjustment of the steering wheel, this measure also enables the longitudinal adjustment in the axial direction of the steering shaft.

Die Stelleinheit 2 ist mit ihrem im eingebauten Zustand dem nicht gezeigtem Lenkrad oder dem Fahrzeugheck zugewandten ersten Endbereich 10 an der Halteeinheit 6 angelenkt, die ihrerseits mit dem nicht gezeigten Fahrzeugchassis fest verbunden ist. Die Verbindung zwischen dem ersten Endbereich 10 der Stelleinheit 2 einerseits und der Halteeinheit 6 andererseits erfolgt durch eine komplexe Hebelvorrichtung 11, umfassend einen die Stelleinheit 2 von der Oberseite her U-förmig umgreifenden Brückenabschnitt 12, der über einen Bolzen 13 an der Halteeinheit 6 angelenkt ist und sowohl auf der rechten als auch auf der linken Seite der Stelleinheit 2 in zwei in Richtung des nicht gezeigten Lenkrades (nach hinten) ausgerichtete Schwenkhebel 14 übergeht, die ihrerseits mittels eines Bolzen 15 an der Stelleinheit 2 angelenkt sind. Des Weiteren besitzt die Hebelvorrichtung 11 auf der in Fahrtrichtung links liegenden Seite der Stelleinheit 2 einen gegenüber dem Schwenkhebel 14 abgewinkelten, sich nach unten erstreckenden Antriebshebel 16, der an eine mit einem Innengewinde versehenen Spindelmutter 17 angelenkt ist. Die Spindelmutter 17 sitzt auf einer mit einem Gewinde versehenen Spindel 18, auf der sich die Spindelmutter 17 relativ zur Stelleinheit 2 nach vorne oder nach hinten verschiebbar ist, wenn sich die Spindel 18 dreht. Die Spindel 18 wird durch einen ersten Elektromotor 19 über ein nicht gezeigtes Getriebe angetrieben.When installed, the
Um die Lenkwelle 4 und damit das nicht gezeigte Lenkrad in Schwenkrichtung 20 nach oben oder unten zu verstellen, wird der erste Elektromotor 19 in einer ersten Drehrichtung eingeschaltet, wodurch sich die Spindel 18 ebenfalls in einer ersten Drehrichtung dreht. Dabei wird die Spindelmutter 17 auf der Spindel 18 beispielsweise aus der in

Ein zweiter Endbereich 21 der Stelleinheit 2 ist im Einbauzustand der Lenksäule 1 mittels eines erfindungsgemäßen Bügelelements 8 am nicht gezeigten Fahrzeugchassis befestigt. Das Bügelelement 8 ist aus einem Stahlblech gebildet und weist einen Befestigungsabschnitt 22 und einen Biegeabschnitt 23 auf. Der Biegeabschnitt 23 erstreckt sich parallel zu einer Ebene, wobei die Ebene gegenüber der Drehachse 9 im lastfreien Zustand des Bügelelements 8 orthogonal ausgerichtet ist. Der lastfreie Zustand ist jener Zustand, in dem das Bügelelement 8 verformungsfrei ist, also nicht elastisch verformt ist. Der Biegeabschnitt 23 erstreckt sich seitlich über die Breite der Stelleinheit 2 und ist in seinem unterem Endbereich 26 mit Durchgängen für Befestigungsschrauben 24 versehen, mittels derer das Bügelelement 8 an der Stelleinheit 2 verschraubt ist. Bevorzugt ist die Biegeabschnitt gleichbreit oder breiter als die Stelleinheit 8. Der untere Endbereich 26 ist außerdem in einem zwischen den beiden Durchgängen für Befestigungsschrauben 24 befindlichen Abschnitt mit einer kreissegmentförmigem Ausnehmung 25 versehen, um für die Bewegung nicht gezeigter, mit der Lenkwelle 5 verbundener Lenkwellenteile einen Freiraum zu schaffen, wie beispielsweise einem Universalgelenk. Des Weiteren ist der Biegeabschnitt 23 mit einer zentralen Ausnehmung 27 versehen, die zur Verringerung der Biegesteifigkeit des Biegeabschnitts 23 dient. Die Ausnehmung 27 erstreckt sich über eine Biegekante hinweg, wobei die Biegekante zwischen dem Biegeabschnitt 23 und dem Befestigungsabschnitt 22 ausgebildet. Innerhalb der zentralen Ausnehmung 27 ist eine kreuzförmige Verstrebung 28 angeordnet, welche eine Verbiegung des Biegeabschnitts 23 in andere als den gewünschten Richtungen erschweren soll.When the steering column 1 is installed, a
Die kreuzförmige Verstrebung 28 umfassen einzelne Streben, die als Zugstäbe ausgebildet sind, wobei sich die einzelnen Streben in einem zentralen Punkt treffen und in diesem zusammenlaufen. Durch die kreuzförmige Verstrebung 28 ist die Steifigkeit der Lenksäule in Richtung der Schwenkachse 31 erhöht.The
An seiner Oberseite geht der Biegeabschnitt 23 in einen abgewinkelten Befestigungsabschnitt 22 über, welcher mit seitlichen Durchbrüchen 30 zum Durchgang von Befestigungselemente versehen ist, mit denen der Befestigungsabschnitt 22 am nicht gezeigten Fahrzeugchassis verschraubt werden kann. Der Winkel zwischen Befestigungsabschnitt 22 und Biegeabschnitt 23 richtet sich nach den baulichen Gegebenheiten des Fahrzeugchassis, wobei die Fläche des Befestigungsabschnitts 22 im Wesentlichen parallel zur gegenüberliegenden Befestigungsfläche des Fahrzeugchassis ausgerichtet sein sollte. Der Winkel zwischen dem Befestigungsabschnitt 22 und dem Biegeabschnitt 23 weist bevorzugt einen Wert zwischen 75° und 110° auf.At its upper side, the bending
Wenn sich bei Betätigung der Höhenverstellung der hintere Lenkwellenteil 4 und der erste Endbereich 10 der Stelleinheit 2 in Schwenkrichtung 20 verschwenkt, so erfolgt diese Schwenkbewegung um eine Schwenkachse 31, deren ungefähre Lage in
Beispielsweise liegt eine durch die Rotationsachsen der Bolzen 13 und 15 gezogene Linie bei der Darstellung von
Anders sieht es aus, wenn die Höhenverstellung in Schwenkrichtung 20 ganz nach unten (
Durch die erfindungsgemäße Ausgestaltung ermöglicht das Bügelelement 8 elastische Verformungen, die sowohl eine vertikale Verschwenkung als auch eine axiale Verschiebung der Stelleinheit 2 zulässt.Due to the configuration according to the invention, the
Das Bügelelement 8 ist bevorzugt als Stanz-Biegeteil ausgestaltet. Dies ermöglicht eine besonders kostengünstige Herstellung. In der vorliegenden Ausführungsform weist das Stahlblech des Bügelelements 8 eine Dicke von etwa 1 mm auf. Dabei erlaubt es eine Verschwenkung der Stelleinheit 2 bis zu 5° (+/- 2,5°) sowie eine axiale Verschiebung um bis zu 5 mm, ohne den elastischen Spannungszustand zu verlassen, so dass das Bügelelement 8 in einem lastfreien Zustand in seine ursprüngliche Gestalt zurückkehrt. Die Verformung ist somit reversibel.The
In der vorliegenden Ausführungsform ist das Bügelelement 8 sowohl an der Stelleinheit 2 als auch am Fahrzeugchassis mittels Befestigungsschrauben befestigt. Statt der Befestigungsschrauben kommen aber auch andere Befestigungsarten wie Niete, Klemmverbindungen, Formschluss (Umklammerung), Verformung von Befestigungselementen und Verkleben infrage. Des Weiteren kann das Bügelelement 8 mit der Stelleinheit 2 auch unlösbar verbunden sein, beispielsweise durch Fügeverfahren wie Schweißen oder Löten oder indem das Bügelelement und die Stelleinheit als einstückiges integrales Bauteil ausgestaltet sind. Im letztgenannten Fall kann man die Befestigungselemente einsparen.In the present embodiment, the
Neben der Höhenverstellung verfügt die gezeigte Lenksäule 1 auch über eine elektromotorische Längsverstellung. Diese ermöglicht die Verschiebung des Mantelrohrs 3 gegenüber der Stelleinheit 2 in Axialrichtung parallel zur Drehachse 9 der Lenkwelle 4, 5. Dabei ist das obere Lenkwellenteil 4 im Mantelrohr 3 mittels Wälzlagern drehbar gelagert, so dass es sich bei einer Verschiebung in Axialrichtung zusammen mit dem Mantelrohr 3 bewegt. Das untere Lenkwellenteil 5 ist mit dem oberen Lenkwellenteil 4 drehfest aber in Richtung der Drehachse 9 teleskopisch verschiebbar verbunden. Das untere Lenkwellenteil 5 ist mittels eines Wälzlagers 34 im zweiten Endbereich 21 der Stelleinheit 2 drehbar gelagert. Für die Längsverstellung in Richtung der Drehachse 9 ist ein elektromotorischer Antrieb vorgesehen, der einen zweiten Elektromotor 35 aufweist, welcher über ein nicht gezeigtes Getriebe und einen zweiten Spindeltrieb 36 das Mantelrohr 3 in Axialrichtung gegenüber der Stelleinheit 2 verschiebt.In addition to the height adjustment, the steering column 1 shown also has an electric motor-driven longitudinal adjustment. This enables the
Die erfindungsgemäße Lösung ermöglicht bei einer Lenksäule 1 mit motorischer Höhenverstellung auf einfache und kostengünstige Weise eine schwenkbare Befestigung der Stelleinheit 2 am Fahrzeugchassis bei gleichzeitigem Längenausgleich mittels des erfindungsgemäßen Bügelelements 8.In the case of a steering column 1 with motorized height adjustment, the solution according to the invention enables the
